[flexcoders] How to trigger the faulthandler of a httpservice

[max.bruchmann]

Hi,
Is it possible to trigger the fault handler of httpservice from the
server. 
I'm using php on the backend and in case some database connection
error occurs I want to send this to the fault handler.
Is this possible or should I use the resulthandler with some if else
statement

thanks in advance
cheers
